Process Heat Exchangers: Applications and Rules-of-Thumb Short Course  (US$1200)

Instructor: Tom Lestina

Why select a horizontal instead of a vertical thermosiphon? How do you size a heat exchanger for an application? How much margin should you select? What are typical operating problems?

This course focuses on developing design checklists and rules-of- thumb to help engineers avoid common problems in process heat transfer. It surveys common heat exchanger types used in the process industry including shell-and-tube, air-cooled, plate-frame, and plate- fin exchangers. Fundamentals of heat transfer and pressure drop are provided for single-phase, boiling, and condensing services. Selection criteria for common applications are discussed, guidelines for thermal design are provided, and detailed examples are summarized. Industry case studies of thermal design and operational problems are presented and lessons learned discussed.

A copy of Process Heat Transfer: Principles, Applications, and Rules of Thumb, by Robert Serth and Thomas Lestina, is included with the course and serves as the primary reference for course material. Engineers who have recently graduated and more experienced engineers who are responsible for design and operation of process heat exchangers will find this course valuable.

Key Topics

  • Types and applications of heat exchangers
  • Fundamentals of heat exchanger performance
  • Heat exchanger selection criteria
  • Single-phase applications and performance
  • Boiling applications and methods
  • Condensing applications and methods
  • Operational problems
  • Troubleshooting heat exchanger operation

Suggested Participants

Engineers—from novice to expert—who want to improve their design process and checklists

Course Credits: 12 hours (PDH/CEU)

Xist Workshop  (US$450)

Instructors:

This workshop is devoted to the shell-and-tube exchanger geometries handled only by Xist. The course focuses on the extensive options available in Xist and how you can use these methods effectively to solve several example problems. You will leave the class knowing how to take full advantage of the features this robust tool offers.

Key Topics

  • Overview of Xist interface and the benefits of HTRI methods
  • Process specifications rules for rating, simulation, and design
  • Guidelines for specifying fluid properties
  • Description of Xist geometry input parameters and their defaults
  • Interpretation of Xist outputs for validation of unit performance

Suggested Participants

Designers of shell-and-tube heat exchangers and process engineers who evaluate their performance

HTRI Software

This course will make use of the following HTRI software: Xchanger Suite® component Xist®. All training materials are based on the current software version.

Course Credits: 6 hours (PDH/CEU)
